Thatcher arrived in Arizona via San Diego midway through the 2013 season. The 32-year-old left-handed reliever had 37 appearances with the Diamondbacks so far in 2014, boasting a 2.63 ERA and 25 strikeouts in 24.0 innings pitched.

Campana, a left-handed hitter, had 60 at-bats with the D-backs in 2014, hitting just .150 with one double, one triple and three RBI.

The trade has the Diamondbacks receiving a right-handed pitcher and a left-handed hitting outfielder from the minor leagues.

Krehbiel, a 6-foot-2 reliever, pitched in 17 games for a Class-A and a Class-A Advanced club in the Angels’ farm system this season. The 21-year-old struck out 23 batters and had a 2.00 ERA with five saves in 18.0 innings pitched.

Borenstein, a 6-foot, 225-pound leftfielder, has appeared in 78 games between the Angels’ Double-A and Triple-A affiliates in 2014. For the Salt Lake Bees of the Pacific Coast League, the 23-year-old Borenstein batted .256 with two home runs and 22 RBI in 117 at-bats.

In addition to the trade Saturday, the Diamondbacks recalled left-handed relief pitcher Eury De La Rosa from Triple-A Reno, who has appeared in 19 games so far for the D-backs in 2014.
